It has been hard work but I now have a Rev A iMac dual-booting MacOS9 and Debian 3.0r2. I am using the 2.4.18-newpmac kernel. I have not installed X windows. I have searched the mail archives and read many emails, some helped (which is why I have a working system), and some went right over my head...
The current list of problems is:- 1) CTRL-ALT-DEL causes system reboot. I have to type "shutdown -h now". 2) no modem. Can the internal iMac modem work under Debian? Should I buy an external USB modem? Should I buy something that fits on the Ethernet port? 3) I did have X windows working, but there was no way I could shut the system down. I turned it off at the mains (bad thing!). Then I had to do a complete re-install but chose not install X. How do I setup X windows so that I can type "startx" or "initx" at the prompt? I do NOT want X starting automatically. How do I set it up so that I can shutdown X and get back to the prompt so I can shut the system down? 4) how do I set up "sudo" so I can login as me and install stuff without logging out and going back in as root? 5) Should I be using a later 2.4 or 2.6 kernel? I have no signs of the display problems reported by other CRT iMac users. I think that is enough for now! Dave Turner
